A pilot experienced an engine power loss at 150 feet during takeoff. Unable to autorotate, he performed a run-on landing, sliding 40 feet before the aircraft rolled onto its side. Examination found no mechanical malfunction.

Narrative

The pilot reported that the aircraft was preflighted, started, and warmed up with temperatures and pressures gauges in the green. Following the engine warm-up, the pilot began a hover, cleared the area, and proceeded to takeoff. Approximately 150 feet after lift-off, the engine stopped producing power. The pilot was traveling between 30 and 50 mph at the time. He attempted a quick-stop but determined he was too low and did not have enough altitude to autorotate the aircraft. Instead, he executed a run-on landing. After contacting the ground, the aircraft slid approximately 40 feet. As it came to rest on a terrace, it slowly rolled onto its side.

Examination

An examination of the aircraft did not disclose evidence of mechanical malfunction. No further information regarding the cause of the power loss was provided in the report.
